前言目前由于吊臂结构型式的改进,以及高强度钢的应用,不增加吊臂自重的情况下,提高了起重量,因此轮式起重机正向大吨位高速度发展。高速度是指行驶性能,要具备越野行驶的优点,又具备汽车式的行驶速度。起重机行驶时的振动情况是很复杂的,影响因素很多,如路面状况,车辆结构,行驶速度的变化等。其中悬挂的弹性,阻尼和悬挂质量的大小,是决定行驶平顺性好坏的重要因素。在设计计算起重机底盘悬挂时,控制机
Foreword At present, due to the improvement of the boom structure type and the application of high-strength steel, the lifting weight is increased without increasing the weight of the boom. Therefore, the wheeled crane is developing at high tonnage and high speed. The high speed refers to the driving performance, the advantages of off-road driving and the car-like driving speed. The vibration situation when the crane is running is very complicated, and there are many influencing factors, such as the road conditions, the structure of the vehicle, changes in the speed of travel, etc. The elasticity of the suspension, the size of the damping and the suspension quality are important factors in determining the smoothness of the ride. When designing and calculating crane chassis suspension, control machine
